Ty for the video! Idea one sounds interesting to test. Maybe someone can take you  up on it. 

Idea 2 sounds very close minus the chat gpt stuff to a client I teased (design only) that is all for audio notes. If you see my notes there’s one long one with a bunch of links and one of them is NED. 

Idea 3 exists already I think. We have bounty client on nostr where you can zap bounties that you feel are good ideas. Actually I don’t remember if the zap comes out right away or just says you owe this much. It would be easy to get scammed if you zap a stranger right away. I forget the client name but it might be on nostrapps.com
